Hello,

I need to replace the MB battery in my 84 300CDT, do I need to purchase a MB battery or can I go to Auto Zone or Sears? How about an optima red top battery?

Thanks,

I've had no problems getting batteries at the auto stores. I don't think they have them at WalMart. Batteries are batteries. Just make sure the dimensional size is correct as well as CCA. The diesels like a stronger battery.

Interstate. They will work great because they are rotated in stock, so they dont sit on the shelf long, and they have a prorated warranty. If you ever have to use it. MB99 is the number you want.

I'd vote for the Interstate battery, or a replacement Mercedes Benz battery.

But for a beater car anything from Costco or Autozone would be all right.

Yes, Interstate is the brand. Call around, I bought mine (2-3) at Advanced or Auto Zone. Can't remember right now.

You must be a used car sales person not worried about beng stuck on the side of the road.
FYI: if you did not know, Wallmart is a very bad company. It accually lowers the economical standard of any city or town it moves into. You might think you are just "saving a buck" shoping at such a place, but in reality you are moving the american standard worldwide lower. Do a little research and you will see buying local supporting the people that reinvest money back into your community is the best gottdamn thing you can do. To put it blunt.

Uh, did you read what you just quoted dimwit. Was I f--in recommending Walmart. Did they fire you or something bro. I live in a small town. You ain't telling me sh**.

Just as I thought, I'll see if I can pick one up tomorrow.

I found the battery on the Interstae site, model MTP-93 :

Cranking Amps 1000
Cold Cranking Amps 850

I'll take the old battery with me just to make sure that size is the same and the CCA is the same.

Thank you for the input!!

Right their....... cant you see,

I guess not.
Sorry, I read that wayyyyyy wrong. I just can hold my mouth shut when it comes to places like that(wallmart)

I've used Interstate as well as the auto parts store brands in my diesels. They all work well for a few years, than you just need to spend another $80 and replace them again. I don't see any compelling reason to buy MB batteries. Batteries are just wear items that need to be replaced periodically, regardless of brand.

No problem. Places like walmart and home depot are convenient, but they have closed down a bunch of not only mom and pops but some of the other chains that have been around alot longer with better products. I too don't care for them.

I put genuine white-case MB batteries in mine just because I like the way they look...not the same as a bright yellow one from WalMart...

I called Fairfield MB and a local Interstate battery dealer(Interstate part#MTP-93), I was quoted $125.00+tax for the batteries.

At this point, for the same price I agree with davestlouis and I'll get the MB battery.

Thanks again for all the input

The best battery I've ever purchased is made by a company called East-Penn.

The battery is Deka.

They are not widely available, but are very well made and if you search the WEB, you'll find them praised in more than one place.
